Deleting a user from IDD & impact on qfiles?

I have returned to IDMS DBA work after > 10 years away & am 'relearning' how to do things. One task I have is to clean-up old user IDs using IDD & OCF. I have come across a few users who are registered for qfiles - typically as:

*+ REGISTERED FOR ALL OF *+ QFILE 'NEW HEMPLYRS' VERSION 1 *+ WITH RESPONSIBILITY FOR CREATION UPDATE DELETION

I understand the 'definition' above, but for some reason, I remember, maybe incorrectly, that you need to be careful deleting a user who is registered for a qfile. That is, the qfile may become 'invalid / inoperative', or worse, be dropped, if the user is the only registered user for the qfile? I tried to display one of the qfiles in question to see if other users were registered for the qfile, but received:

DC601081 USER NOT REGISTERED FOR FUNCTION AGAINST THIS ENTITY OCCURRENCE

So, my questions: 1) if a user is dropped from IDD & is the only user registered for a qfile, is the associated qfile dropped as well?; and 2) if the qfile will be dropped, how can I display the qfile without the DC601081 & then register another user for it if needed?

Sorry if this is a 'stupid' question and/or if I have it completely wrong, but I want to be sure before I drop the users. Thanks for reading this & for any help/insight you can provide, I appreciate it.

Absolutely,and then that user can reassign the object to another user. That other user can be one that never signs on, basically, a place holder. We do that with our source modules for our dialogs to stop them from being updated with them being officially assigned to a programmer.

I suspect the cause of the DC601081 is that PUBLIC ACCESS IS NONE has been set for the Qfile - so you need to follow John's advice of "set opt reg override" so that you can even DISPLAY the Qfile. Once that is set - it may be worthwhile setting PUBLIC ACCESS DISPLAY so that this is not a problem for either yourself or others in the future.

I believe that if you try to DELETE the last User REG FOR ALL for any entity in the dictionary - IDD does warn you and prevents you from doing this. Another thing - the DROP USER for OCF operates independently of the DEL USER from IDD. OCF will remove the User from the User Catalog, DEL USER removes the specified User entity from the Dictionary that you are currently signed in to.
